# About this product

AI System Characterization Checker is a free reference, matrix and readiness check for ISO/IEC DIS 42102, with a paid descriptor kit and change watch. It is built and run by The Art of Service.

## Why it exists

AI governance leads and ISO/IEC 42001 implementers are asked to describe systems that their organisations do not fully understand. The inventory records a vendor and a use case. The policy uses words like model and capability without fixing what they mean. The draft offers a way out: two axes, a defined vocabulary and a matrix that can be filled with evidence.

## Who it is for

The AI governance lead who owns the policy, the ISO/IEC 42001 implementer who owns the management system, the procurement lead who writes the supplier schedule, and the assurance lead who has to show that a word means the same thing in four documents.

## How the record is built

From the official ISO catalogue record, the public preview in the Online Browsing Platform and the national body project pages that carry the stage date. Every line is written in our own words and cited to its clause. No draft text is reproduced. The method page sets out the claim levels and the limits.

## What backs the evidence guidance

Three AI standards behind the evidence guidance: ISO/IEC 42001:2023 for the management system, ISO/IEC 23894:2023 for risk and ISO/IEC 42005:2025 for impact assessment. Their controls are exported at build time and crosswalked on the matrix page, so the evidence guidance points to rules that already exist rather than to an opinion.

## Who writes it

Gerard Blokdyk, The Art of Service. The product is independent of ISO and IEC and is not endorsed by either. Contact support@theartofservice.com.

## What it will not do

It will not tell you that you are compliant, will not reproduce the draft, will not invent the descriptor wording or the annex titles, and will not treat a planning date as an ISO deadline. It is a reference and a planning aid.
